BUFFER FOR PlCKER-S'TAFFS OF LOOMS.

SPECIFICATION forming part of Letters Patent No. 443,524, dated. December 30, 1890. Application filed May 4, 188% Serial No. 309,641. (No model.) Patented in England June 17, 1889, No. 9,928.

To all whom it may camera.-

Be it known that 1, JAMES INGRAM, of Lawrence, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Buffers for Picker-Stafis of Looms, (for which I have obtained Letters Patent of Great Britain, No. 9,928, dated June 17, 1889.) of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents an enlarged section of this improved bufier. Fig. 2 represents a plan thereof, on a smaller scale, in section and as applied to the end of the loom.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to buffers for cushioning the blow of the picker-staff against the race; and it consists in certain novel features hereinafter fully described and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

The body of the buffer consists of a hollow box no, the chamber y of which is preferably rectangular in cross-section. One end of the chamber is open at a and its opposite end provided with a bolt-hole g, in which the bolt tis fitted to slide. A horizontal lip or flange 15 projects laterally from the body 00 and is provided with bolt-holes 16, whereby it may be adjusted on the frame A, as shown in Fig. 2.

The body m of the buffer proper H is fitted to slide in the chamber y, and is secured by its inner end to the bolt t, around which a coiled spring w is disposed.

The head 1) of the buffer proper projects horizontally at right angles from the outer end of the body wt, and a cushion of leatherplates a is secured to the outer face by a bolt 17.

In the use of my improvement the stafi B on its stroke strikes the cushion r of the buffer proper, forcing it inward into the body against the pressure of the spring w, which serves to cushion or lessen the force of the blow. The bolt 11 at the same time slides in the opening g, and its head 4;, engaging the end of the box 0:, serves as a stop for the buffer when returned by said spring. The flexible cushion 1 also prevents wearin g of the staff at the point where it engages the buffer. By checking the blow of the staff, as described, it is relieved from the constant jar and concussion to which it is subjected when permitted to engage the end of the frame or an unyielding buffer in the ordinary manner.

Having thus explained my invention, what I claim is 1. In a buffer, the combination of an elongated hollow body provided with a lateral flange at one side for attachment to a loomframe, a bolt fitted to slide in one end of said body, a buffer proper secured to the stem of said bolt and sliding in the opposite end of said body, a cushion of flexible material secured to the outer face of the buffer proper, and a coiled spring disposed around said bolt within the body.

2. In a buifer for picker-staffs, a body provided with a rectangular chamber open at one end and having a bolt-hole in the opposite end and an attaching-flange thereon, a bolt sliding in said hole, a buffer proper having a head at right angles to its body and secured to said bolt, a flexible cushion 011 said head, and a coiled spring disposed within said chamber around said bolt, substantially as described.

JAMES INGRAM.
